I I i Finn Lass Appl ication'fileii rune-T19, raga-s mi ThisinVentiOnrelates to fire'less "cookers andinore especially to heat accumulatorsof novel construction for use in connectionwith utensils in the cooker,the heat accumulators and utensils being so constructed as to be nestedreadily to secure the greatestpossible efliciency.

Another object is to provide heat accumulators so constructed that airis permitted to circulate freely through them, thus quickly to dissipatethe heat contained within the accumulators so that they can be usedtothe best advantage'in cooking food within the apparatus. v

With the foregoing and other objects in view which will appear as thedescription, proceeds, the/invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodimentv of the invention herein disclosed may be made within thescope of what is claimed, without departing from the spirit of the.invention.

In the accompanying drawings the preferred form ofthe invention has beenshown.

In said drawings V v I Figure 1 is a vertical section through a portionof a cooker having the present improvements combined therewith.

c Figure 2 is aplan view of one of the heat accumulators. 1 p

Figure 3'is a bottom view thereof.

Figure-4 is a section on line 44, Figure 2.

vFigure 5 is a section on linen-5, Figure 2.

Referring .to the figures by characters of reference 3 designates aportion of a fireless cooker in which is arranged an inner lining 13,suitably insulated as at 16, '17, 18' and 19 and providingawell 14. LA.gutter 10is arranged within the-upperportion of the this gutter.

The well is open at the top as indicated at 8 so as to receive a cover22 provided with insulators 23, this cover being formed with a marginalflange '9 adapted to rest upon the top of the cooker structure. Aremovable lining 12 is adapted to be supported in the well 14 by meansof a bead 11 extending therearound and resting in the gutter 10. Thisremovable lining is designed to receive those parts of the structureconstituting the present invention. Said no. seams. Renewed April 30,"1927,

structure includes heat accumulators 40 and uten'si'ls41whichcanbeplaced in superposed relation. As shown in the drawings each of thesehot plates is preferably formed with a'fiat top 42 andwith a concavedbot from face '43, there beingspaced supporting lugs '44 projecting fromthe marginal por tions ofthe concaved face- Openings 45 extend throughthe hot plates and extending into the periphery of the hot plates atdiametrically opposed points are sockets 46.

These sockets areadapted to receive fingers 47 extending'inwardly ortoward each other from the ends of a'bail 48. The bail is sub stantiallysemi-circular. and normally rests in amarginal recess 49 formed in thefiat the circumference of theplate. A recess 50 is formed in the topface 42 of the hot plate andis' adapted 'to be bridged normally by thebail 48. By inserting a suitable lifting face of the hot platealongabout one-half tool inthe recess '50 the bail can be readilygripped and the hot plate thus carried conveniiently to place it in orremove it fromthe wel Each utensil 41 is preferably provided with acover such as shown at 51 in Fig-- ure l.-' Each cover has a centralconcavoconvex portion 52'surrounded by a flange 53 which is tapered soas to fit snugly in the open end of the utensil. The outer marginalportion of the fiange is outturned asat 54 to rest on the utensil and isadapted to be engaged by retaining devices 55 secured to the wall of theutensil. I

A large heat accumulator 40 is adapted to be placed on the bottom of thewell as shown in Figure land will support one of the utensils 41. Afterthe cover ,52 has been placed in position a smaller heat accumulator isplaced thereon and will support another utensil 41 as shown in'Figure 1.By

providing the openings45 and the spaced supporting lugs 44 air is'freeto circulate through the heat accumulators and the heat in saidaccumulators will thus be quickly dissipated so as rapidlyto raise thetemperature of the contents of the well. What is claimed is: V 1. In afireless cooker a heat accumulator having a flatupper face and aconcaved lower face, there being openings extending through theaccumulator, and spacing lugs supporting the plate.

2. In a tireless cooker a heat accumulator I at the periphery of theconcaved face for 1110 having a flat upper face and a concaved low orface, {there being apertures extending through the accumulator, spacedsupporting lugs on the accumulator, a bail having inturned fingersrotatahlv seated Within chainetrically opposed portions of theaccumulator, said accumulator having a marginal recess for receiving thebail to support it be low the plane of the flat face of the accumulator;t

3. In a tireless cooker a heat accumulator having diametrically opposedIHtlltll sockets and a iinarginal recess terminating at the sockets, anda lifting hail normally seated in the marginal recess and havingterminal fingers rotatahly mountecl'in the sockets, there being a recessin one face of the accumulator and extending" under the bail, andintersecting the marginal recess.

In testimony that. I claim the foregoing as my own, I have heretoafiixetl my signature.
